Academics and colleagues are rallying around a California university professor who was arrested and charged with assaulting a federal officer during a chaotic immigration raid at a cannabis farm that resulted in a worker's death.

John Caravello, a math and philosophy professor at California State University Channel Islands, joined a crowd of protesters who confronted immigration agents when they arrived at Glass House cannabis farm in Camarillo, a community about 50 miles north of Los Angeles.
